sPEcIrIoArIoN forming part of Letters Patent No. 550,609, dated December 3, 1895.

Application filed March 8, 189 1. Serial No. 502,809. (No model.)

To all whom it may concern.- Be it known that I, ALBERT C. GETTEN, a citizen of the United States, and a resident of Sandy Hill,Washington county, State of New York, have invented certain new and useful Improvements in Fluid-Supplying Devices, of which the following is a specification, reference being had to the accompanying drawings, forming part hereof. I o This invention relates to devices for supplying fluids to machines in which these fluids are to be used; a

My invention has been embodied in connection with paper-bag machinery and in I 5 means for supplying paste to the paste boxes.

or reservoirs of such machines, and I will particularly describe herein the best means that I have adopted in thus carrying my invention into practice. 2o Paper-bag machines use large quantities of paste. Each machine is usually provided with two paste boxes or reservoirs, from which the paste is fed to and suitably applied upon the bags made bythe machine. One'of these 2 5 paste-boxes is designated the center-seampaste box and the other is designated the head or bottom paste box. Each one of these two paste-boxes in some factories uses paste of a different consistency, the center-seam paste 0 being quite thin and the head-paste quite thick. Prior to my invention these pasteboxes were filled by the operatives as occasion required by pouring the paste into the boxes from pails. Each machine had two 3 pails, one for the head-paste and one for the center-seam paste, and these pails were replenished from a suitable mixer and reservoir. This procedure was extremely wasteful, uncleanly, and unsatisfactory. The paste would 40 be spilled about on the floor, and it would become hard and dry from exposure to the air on the sides of the pails. To keep the paste in proper condition, it was necessary to Wash out these pails every day, and this work of cleaning was extremely laborious and wasteful of the paste. In large factories having thirty or forty machines the wastefulness of the old method was especially notable and all the objectionable features above noted were more strongly accentuated. There was also another and great objection to the old method, and it was that frequently, through the carelessness of the attendants, the paste-boxes in the machine would run dry for periods som etimes of a few minutes, sometimes longer, and 5 5 hundreds and even thousands of bags would be properly folded and apparently properly made, but withouta particle of paste upon them, and these bags would be packaged, shipped, and delivered without discovery of their defect until in the hands of the user. This latter objection is a most troublesome one in business arrangements, and, notwithstanding the greatest care in supervision of the operatives, was not overcome until the present invention substituted in place of the manual work of the operatives automatic means for uniformly conveying to the pasteboxes a regulated supply of paste.

In the embodiment of my invention herein described the paste is conveyed by a conduit from amain reservoir to the several machines in which it is to be used, and means are pro vided for regulating the quantity of paste supplied to each paste-box in accordance with the 7 5 rate of consumption in each machine, said means being controlled by the movements of the respective machines and operated by some moving part of the machine.

As paste is a thick and somewhat viscuous fluid, it is more difficult to manage and control than a thin fluid; but in the means embodying my invention the paste is allowed to flow in considerable volume for short periods of time, and this is repeatedat intervals in 85 the operation of each machine. This is accomplished by providing a cook or valve in a branch of said conduit, suitably located in proximity to the paste-box of each machine, and operating this cook or valve intermittently by connection with some moving part of the machine, so that the cock or valve at intervals is opened to allow a quantity of paste to flow into the paste-box and is then closed and remains closed for aperiod. These 9 5 operating means are capable of delicate adjustment, so that the degree of opening of the cook or valve or the duration of that opened condition or both degree and duration may be adjusted to correspond with the. rate of consumption of the machine.

For the purpose of supplying the two kinds of paste when required-to wit, the head-paste and the center-seam paste-I have fitted up two supplying and circulating systems, one system connected with a reservoir for the thicker or head-paste and the other system connected with a reservoir for the thinner or center-seam paste, and these two systems are entirely independent of each other and both are operated in substantially the same manner.

The accompanying drawings, to which I will now refer, illustrate embodiments of my invention.

Figure l is an end elevation of a portion of a paper-bag machine, including the centerseam paste-box, and showing a portion of the conduit and my improfid means for regulating the supply of paste to the paste-box. Fig. 2 is a part plan view of the same. Fig. 3 is a side elevation showing a modified construction of the device for operating the cook or valve, and Fig. 4 is a plan view of a portion of the same. Fig. 5 is an end'elevation show-. ing a head-paste box anda portion of 13116-00111 duit and a construction of my improved'means for regulating the supply of paste to this paste-box. Fig. 6 is an enlarged, sectionalview of the adjustable tappet or cam. Fig. '7 is an elevation on a reduced scale showing a main reservoir and a portion of the conduit and the means for circulating the paste in said conduit.

The main reservoir a, Fig. 7', inthe-embodiment of my invention shown is. charged with paste and is provided with suitable d'evi'ces-.

such as the rotating armsb, operated by the vertical shaft cto keep the paste properly mixed and-of uniform consistency and'to pre; vent the formation of lumps. therein. The conduit d extends from the lower part ofsaid reservoir a and isprovided with branches ff,

extending in proximity to the respective ma-.

chines, and this conduit returns to themain reservoir a, so as to carry the excess Off paste back to the reservoir, as shown. duit cl has interposed therein a force-pump d, operated by the crank d on the shaft d The shaft d is suitably operated" and maybe connected with the vertical. shaft 0 by bevel;- gears 0 0 as shown, or otherwise, or the two shafts d and 0 may be independently operated inany suitable manner. A, check-valve at e co-operates with the pump-piston in forcing the paste through the conduit, and an airchamber e performs. the usual function, of]

such devices. The conduit preferably in,- clines slightly downward from the point at which the air-chamber e is located, so. that gravity will assist the flow of the-paste therethrough and so that the conduit will drain itself when water or fluid is used to wash it.

Fig. '7 illustrates the circulating system for either center-seam or head paste. WVhen these The con-.

two consistencies of paste are to be supplied, the system shown in Fig. 7 is duplicated, and thus two. separate systems,. each like that shown in Fig. 7, are employed, one of the systems having branches in proximity to the center-seam-paste boxes of the machines and the other system having branches in proximity to the head-paste boxes of the machines.

It is, of course, evident that other arrange ments than those shown may be employed and that the paste may be forced through the conduit by gravity or other pressure-producing means or in any other suitable manner.

The branches ff of the conduit are shown in Figs. 1 and 5 in their proper relation to Twill-first describe the construction shownin Figs. 1' and 2 of the devices for regulating the supply of paste to the-boxes. The pastebox g (shown in Fig. 1) is that employed for supplying the center-seam paste of the bag andeo'ntains theusual rotating paste-supplying disk g. The strip of paper z'from the roll is pulled through the rollers h and h by the other partsof themachine, and thus these rollers are rotated by the friction of the paper. A worm j is secured upon, the end of the upper roller h and meshes with a wormwheel j, having bearings in the bracketpiece 1' which is suitably secured to the frame 7.; of'the machine. Acollar or disklis formed or secured upon the shaft of" the worm-wheel j and is provided with a cam projection or tappet Z", and this tappet Z comes in contact at every revolution with the pivoted lever P. This lever Z is pivoted upon the bracketpieee l and has a: bolt-and slot' connection Z4 with;the bracket piece 7' So as to be vertically adjustable. An adjustable stop Z5 is provided, secured' to the bracket-piece Z and the spring; Z? tends toholdi the pivoted lever Pagainst this stop. The pivoted lever l is connectedby a. rod'mwith an armor handle n of a coclmnof; any suitable and usual construction, which is interposed in the: branch f of the; conduit. I t willbe seen that the tappet Z at every revolutionof the \VOFHLTWIIQGl j will actuate the pivoted lever Z and move it and the rodimin the direction indicated by thearrow, and thismovement will turn the cock m so as'to openthepassage through the same. After the tappet Zf has released the lever Pit. will bepulledjback by the springl to the position shown. During the period when the cock 'n is open a portion of paste willflow into thepaste-box; but this flow willv be checked by the closing of, the cock n. Thusatevery revolutionof the worm-wheel j 'thecock, will be open for a short period and a definite quantityofj'paste willjfiow into the paste-box g. By adjusting the bracket Z the amountof'paste supplied at these times maybe regulated to the desired extent, andby this adjustment the amount of "paste supplied will bemade equal to the amou'ntused in the machine. When the machine is started, the operater will first open the cock at and permit suflicient paste to enter the box to partially or wholly fill the same, and thereafter, as the machine is used, the regulating device wills'upply the amount of paste consumed or used in the operation of the machine, so as to constantly maintain the amount of the initial charge of the paste-box. The connection of the rod m with the arm a permits the rod to be lifted at any time,so to be disconnected from the arm n. A rest or stop 72? is provided to support the rod when it is disconnected from the arm n and to prevent the arm 17, from being moved out of its working position or from falling down. A suitable brace (1 holds the end of the branch pipe fin desired position over the paste-box.

In Figs. 3 and 4. another construction of the devices for operating the cock or valve is shown, adapted to other constructions of paper-bag machines. In this construction a rotat-in g shaft of the machine 72, is provided with a worm j which meshes into a worm-wheel 7' having bearings in the bracket j", secured to the frame of the machine 7c. The tappet or cam in this construction is a plate 0, having an inclined working surface, and is adjust ably clampedto the collar 0, which is formed or secured upon the shaft of the worm-wheel j. The pivoted lever Z is mounted upon the bracket Z and its movement is controlled by the stop 1-" and the spring Z acting in conjunction with the tappet or cam, all in substantially the same manner as described in relation to Fig. 1, and the rod m, which is connected to the arm of the cock or valve, is pivoted to the lever'l below the point at which the lever is pivoted instead of above that point, as in Fig. 1. The extent and duration of the movement of the rod m are adjusted by adjusting the position of the tappet 0 upon the collar 0.

The construction of regulating device shown in Figs. 5 and 6 is adapted to the head-paste box of the machine shown in Fig. 1. Arotating shaft of the machine it is provided with a worm j, meshing in a worm-wheel and an adjustable tappet p is mounted on a collar of the worm-wheel shaft and works against a pivoted lever Z of exactly the same construction as shown in Fig. 1 and controlled by a stop Z and spring 1, also of the same construction as shown in Fig. 1. This lever l is carried by the bracket I, which in this case is not adjustable, as the adjustment is provided by the tappetp, which screws into its collar and has a jam-nutp (see Fig. 6) for holding it in the desired position. A rod m is connected at one end to the lever Z and at the other end to the arm n of a cockn, interposedin the branch f of the conduit, which is arranged above the paste-box 9 A stop a is provided, which performs the same function as the stop at of the construction shown inFig. 1, and the rod m is constructed so that it may be lifted clear of the arm a when desired. A suitable brace q holds the end of the branch pipe fin desired position over the paste-box.

The constructions shown in the drawings and above described illustrate three slightlydifferent structures wherein my invention has been embodied. In applying my improvements to other constructions of machines other modificationswill be made, depending upon the location'and operation of the moving part of the machine to which the regulating device is connected.

It is, of course, evident that other devices than cocks, as shown in the drawings, may be employed for providing a variable opening for the paste or other fluid-as, for instance, valves of suitable construction; also, that other mechanisms may be used to actuate the cooks or valves. 1

In supplying the fluid to the machines in accordance with my invention, as above described, there is practically no waste of the fluid. It does not have to be carried about by hand nor transferred by hand from one receptacle to another. It is circulated within a closed conduit and not exposed to the air while in the conduit, so that it is protected from the drying and deterioration that would otherwise take place. No dependence is placed upon the operator in the work of keeping up the supply to the boxes or reservoirs of the machine, as the mechanism, after having been once adjusted to the rate of consumption of the machine, supplies the fluid in accordance with that rate of consumption, operating periodically when the machine is running and stopping when the machine is stopped, and at all times supplying the fluid in proportion to the rate of operation of'the machine.
